Replacing a front wheel bearing on your 2014 Ford Focus can seem daunting, but with the right tools and knowledge, it’s a manageable DIY project. This article provides a clear path to diagnose a bad wheel bearing and guide you through the replacement process, saving you money and keeping your Focus running smoothly. This article not only tells you how to fix a problem but also shares insights that others might miss.
The first step is confirming that the noise you’re hearing is actually the front wheel bearing. Misdiagnosis is a common and frustrating issue. Listen closely to the sounds your car makes, as it can be a crucial step to solving the problem.
The Tell-Tale Signs
- Noise Increase with Speed: This is the classic symptom. A failing wheel bearing will often produce a grinding, humming, or roaring noise that gets louder as the vehicle’s speed increases.
- Noise Changes During Turns: Pay attention when turning. The noise might disappear or lessen when turning in one direction, and become more pronounced when turning the other way. This indicates the bearing on the opposite side of the turn is likely the culprit. For example, noise disappears when turning left? The right wheel bearing is likely bad.
- Play in the Wheel: Jack up the car, safely secure it with jack stands, and grab the tire at the 12 and 6 o’clock positions. Try to rock the wheel back and forth. Excessive play suggests a worn wheel bearing or other suspension components.
- Vibration: You might feel a vibration in the steering wheel or floorboard, especially at higher speeds.
- ABS Issues: In some cases, a faulty wheel bearing can interfere with the ABS sensor, triggering the ABS light on your dashboard.
Isolating the Problem: Practical Tips
- Road Test: Drive on a smooth, quiet road at various speeds. Try to isolate the noise. Can you determine which side it’s coming from? Does it change with speed or when turning?
- Stethoscope Trick: Carefully use a mechanic’s stethoscope (or a long screwdriver with the handle to your ear) to listen to the hub assembly while the wheel is spinning (safely, with the vehicle on jack stands and the engine off, have someone rotate the wheel). This can help pinpoint the source of the noise.
- Consider Other Possibilities: Don’t immediately assume it’s the wheel bearing. Tire noise, brake issues, and suspension problems can mimic wheel bearing symptoms.
Replacing a wheel bearing requires some mechanical aptitude and the right tools. If you’re not comfortable with this type of work, it’s best left to a professional. But if you’re up for the challenge, here’s a general overview of the process. Gather all the tools necessary to ensure the replacement goes smoothly.
Essential Tools
- Jack and Jack Stands
- Wheel Chocks
- Socket Set and Wrenches (Metric)
- Torque Wrench
- Hammer
- Punch or Chisel
- Wheel Bearing Press Kit (or access to a shop with one)
- Penetrating Oil
- Brake Cleaner
- New Wheel Bearing and Hub Assembly (recommended)
- Gloves and Safety Glasses
Step-by-Step: A Simplified Overview
- Loosen the Lug Nuts: While the vehicle is on the ground, loosen the lug nuts on the wheel you’ll be working on.
- Raise and Secure the Vehicle: Jack up the car and securely place it on jack stands. Remove the wheel.
- Remove the Brake Caliper and Rotor: Detach the brake caliper (don’t let it hang by the brake line – support it with a bungee cord or wire). Then, remove the brake rotor.
- Disconnect the ABS Sensor: Carefully disconnect the ABS sensor wire from the hub assembly. Be gentle; these sensors are easily damaged.
- Remove the Axle Nut: This is usually a large nut in the center of the hub. You may need a breaker bar to loosen it.
- Separate the Hub Assembly: This is often the trickiest part. The hub assembly is pressed into the knuckle. You’ll need a wheel bearing press kit to press it out. Alternatively, you can take the knuckle to a shop that has a press.
- Press in the New Bearing: Using the press kit, carefully press the new wheel bearing into the knuckle.
- Reinstall the Hub Assembly: Press the hub assembly into the new bearing.
- Reassemble Everything: Reconnect the ABS sensor, reinstall the brake rotor and caliper, and tighten the axle nut to the manufacturer’s specified torque.
- Reinstall the Wheel: Put the wheel back on, tighten the lug nuts, lower the vehicle, and torque the lug nuts to the correct specification.
- Test Drive: Take the car for a test drive and listen for any unusual noises.
Why Replacing the Entire Hub Assembly Matters
While you can just replace the wheel bearing itself, I highly recommend replacing the entire hub assembly as a unit. Here’s why, based on my personal experience: Replacing the entire hub assembly makes the process easier and faster in most cases.
- Easier Installation: Pressing the bearing in and out of the hub can be difficult and requires specialized tools. Replacing the entire assembly eliminates this step.
- Reduced Risk of Damage: Improperly pressing a bearing can damage it, even if it’s new.
- Cost-Effective in the Long Run: The hub assembly often includes a new ABS sensor. If your old sensor is corroded or damaged, replacing the assembly can save you the cost of a new sensor later.
- Prevent Future Problems: When a wheel bearing fails, it can damage the hub assembly. Replacing both ensures you’re starting with fresh, undamaged components.
Torque Specifications are Key
Always, always torque all fasteners to the manufacturer’s specifications. This is critical for safety and preventing future problems. Under-torquing can lead to loose components, while over-torquing can damage threads. You can find the correct torque specifications in your vehicle’s repair manual or online databases. Always consult the manufacturer’s specifications to avoid future problems.
I’ve replaced countless wheel bearings over the years, and I’ve learned a few things that aren’t always obvious.
The ‘Sound Mirror’ Effect
Sound can be deceptive in a car. It often seems like the noise is coming from a different location than its actual source. This is especially true with wheel bearings. The sound can travel through the chassis and resonate in unexpected places. To counteract this:
- Have a Passenger Listen: Get someone else to ride with you and listen for the noise. Their perspective might be different.
- Record the Sound: Use your phone to record the noise while driving. Then, listen to the recording later. This can help you focus on the specific characteristics of the sound.
Penetrating Oil is Your Best Friend
Don’t underestimate the power of penetrating oil. Apply it liberally to any rusted or corroded bolts, nuts, and joints well in advance of starting the job. This will make your life much easier and reduce the risk of breaking bolts. I prefer a product like PB Blaster or Kroil. Penetrating oil can loosen stuck components, saving time and frustration.
The Importance of a Good Bearing Press Kit
If you’re going to tackle this job yourself, invest in a quality wheel bearing press kit. A cheap kit can damage the bearing or the hub. Look for a kit with a variety of adapters to fit different bearing sizes. Hydraulic press kits are generally easier to use than screw-type kits.
Diagnosing Without Disassembly
Before you even start taking things apart, try this simple test: With the car safely on jack stands, spin each wheel by hand. Pay close attention to the feel of the wheel as it rotates. A bad wheel bearing will often feel rough or gritty, while a good bearing will spin smoothly and quietly. This can help you confirm your diagnosis before you commit to the repair. Spinning the wheel by hand is a quick way to check for roughness or grittiness.
